In the early weeks after the damaged BP well began gushing huge quantities of oil and gas, a toxic brew was developing deep below the surface in plumes emanating from the wellhead. Finned fish and marine mammals probably steered well clear of the spewing hydrocarbons.

Drumming up anthrax
Mention anthrax and about the last thing that comes to mind is whether there’s a drum in the room. Yet tom-toms — or at least the stretched animal hides on their heads — can sometimes spew toxic anthrax spores into the air.
